After a bit of work I managed to get LiteSpeed to run on a semi production server. I noticed several things along the way and hacked up my own solutions to the problems but I'm curious if these issues are normal or not. Installation dir: /usr/local/lsws cPanel System I was unable to use the build matching PHP from the whm plugin until I compiled PHP5 through the compile PHP option in lsws. I copied the configure line from the cPanel build and put it into lsws and it compiled fine while the matching one would not. After I did this I was able to build the matching PHP. I am not sure if that's normal or not. I also noticed after building the matching php the ini directory was now the cPanel one of /usr/local/lib/php.ini rather the lsws one. The CLI's were not changed upon this build matching configuration. So /usr/bin/php could not use the newly built PDO modules as it threw various errors. I made a symbolic link to /usr/local/lsws/lsphp5/bin/php which I had previously built using the same configure line as the old cpanel apache system. This made so the CLI version had no problems with the PDO extensions. Obviously using /usr/local/lsws/lsphp5/bin/php I had different ini's so I just made a symbolic link to the ini that cPanel makes. So I am wondering is this at all normal? I worked around the problems to make a sane setup to a degree. I can see there being problems if PHP 5.2.9 was to come out. I'd need to build multiple PHP's in order to keep the setup working properly since the CLI version does not match that of what the web server is using. So timing could be a problem.
